fungus in discus

[wendyd]

Hello. A week and a half ago, I noticed white stringy stuff on the fins and tail of my female discus.. the male was fine. I raised the temp to 90, put in salt (metro plus) and the fungus started to fall off. I noticed Sunday that my male discus had fungus on his eye. Treated with maroxy, continued some water change and metro plus. He has lost his eye. The fungus appeared to be gone yesterday, I started on Sunday melafix..
Appears to be some white in the eye cavity again. He is aggressive but eating the female is much better. Should I continue maroxy for fungus? Not sure what to do...
